Academic Activities
1. An experimental study of the distraction of the score by the clue of noun endings and particles on the Korean multiple-choice tests..
2. To better understand the acquisition of Korean as a foreign language, language tests must be able to accurately and reliably measure a learner’s lexical and grammatical ability in Korean. While a dependable lexical ability test has already been developed by Saito and Tamaoka (2014), current grammatical ability tests are lacking in reliability. As such, the current study aims to create an improved Korean grammatical ability test for L2 learners. The test was constructed using 36 question items divided into three sub-categories of morphological inflections, local dependency and complex structure, of which framework was developed by Miyaoka, Tamaoka and Sakai (2014). The grammatical test, along with the lexical test (48 question items), was administered to 84 Chinese and 61 Japanese learners of Korean. The Cormack’s reliability coefficients were 0.872 for the grammatical ability test and 0.881 for the lexical ability test, both showing very high reliability and no language learner group differences. In conclusion, the current grammatical ability test (along with the previous lexical ability test) is effective at providing a reliable and accurate representation of a Korean language learner’s grammatical ability..
3. Developing the lexical knowledge test for learners of Korean as a second language based on the item response theory.
4. A causal relationship between lexical ability and reading comprehension in Korean by native Japanese speakers.
